Abstract

Systems and methodologies are described that facilitate multiplexing communications from multiple downstream access points to one or more mobility management entities (MME). In particular, a concentrator component is provided that can establish a single transport layer connection with an MME along with multiple application layer connections over the single transport layer connection for each of multiple downstream access points and/or related mobile devices. The downstream access points and/or mobile devices can provide identifiers to the concentrator component, which can utilize the identifiers to track communications with the MME. In this regard, the MME can additionally include identifiers received from the concentrator component in subsequent communications to facilitate identifying the appropriate downstream access point and/or mobile device.

Claims

1. A method, comprising:

establishing a transport layer connection with a network component, wherein the transport layer connection supports multiple application layer connections;

receiving, by a mobility management entity, a first unique identifier in an uplink message related to an access point;

inserting, by the mobility management entity, the first unique identifier in an application layer downlink message to facilitate determining the access point related to the uplink message;

transmitting, by the mobility management entity, the application layer downlink message to the network component;

receiving, by the mobility management entity, a handover request message from the network component related to the access point and a target access point;

inserting, by the mobility management entity, a second unique identifier related to the target access point in the handover request message; and

forwarding, by the mobility management entity, the handover request message to the network component or one or more disparate network components.

2. The method of claim 1, wherein the first unique identifier is globally unique to a wireless communications network.

3. The method of claim 2, further comprising including the first unique identifier in subsequent application layer downlink messages related to the access point transmitted to the network component.

4. The method of claim 1, further comprising multiplexing the application layer downlink message with disparate application layer downlink messages related to disparate access points over a single transport layer association to the network component.

5. A mobility management entity, comprising:

at least one processor configured to;

establish a transport layer connection with a network component, wherein the transport layer connection supports multiple application layer connections;

retrieve a first unique identifier in an uplink message related to an access point;

insert the first unique identifier in an application layer downlink message to facilitate determining the access point related to the uplink message;

transmit the application layer downlink message to the network component;

receive a handover request message from the network component related to the access point and a target access point;

insert a second unique identifier related to the target access point in the handover request message; and

forward the handover request message to the network component or one or more disparate network components; and

a memory coupled to the at least one processor.

6. The mobility management entity of claim 5, wherein the at least one processor is further configured to include the first unique identifier in subsequent application layer downlink messages related to the access point transmitted to the network component.

7. The mobility management entity of claim 5, wherein the at least one processor is further configured to multiplex the application layer downlink message with disparate application layer downlink messages related to disparate access points over a single transport layer association to the network component.

8. A mobility management entity, comprising:

means for establishing a transport layer connection with a network component, wherein the transport layer connection supports multiple application layer connections;

means for receiving a first unique identifier in an uplink message related to an access point;

means for receiving a handover request message from the network component related to the access point and a target access point; and

means for inserting the first unique identifier in an application layer downlink message to facilitate determining the access point related to the uplink message, transmitting the application layer downlink message to the network component, inserting a second unique identifier related to the target access point in the handover request message, and forwarding the handover request message to the network component or one or more disparate network components.

9. The mobility management entity of claim 8, wherein the first unique identifier is globally unique to a wireless communications network.

10. The mobility management entity of claim 8, wherein the means for inserting the first unique identifier includes the first unique identifier in subsequent application layer downlink messages related to the access point transmitted to the network component.

11. A non-transitory computer-readable medium comprising instructions executable to:

cause at least one mobility management entity to establish a transport layer connection with a network component, wherein the transport layer connection supports multiple application layer connections;

cause at least one mobility management entity to receive a first unique identifier in an uplink message related to an access point;

cause the at least one mobility management entity to insert the first unique identifier in an application layer downlink message to facilitate determining the access point related to the uplink message;

cause the at least one mobility management entity to transmit the application layer downlink message to the network component;

cause the at least one mobility management entity to receive a handover request message from the network component related to the access point and a target access point;

cause the at least one mobility management entity to insert a second unique identifier related to the target access point in the handover request message; and

cause the at least one mobility management entity to forward the handover request message to the network component or one or more disparate network components.

12. The non-transitory computer-readable medium of claim 11, wherein the instructions are also executable to cause the at least one mobility management entity to include the first unique identifier in subsequent application layer downlink messages related to the access point transmitted to the network component.

13. A mobility management entity, comprising:
